WARNING
For proper operation, the inlet water pressure must be between
140kPa (20psi) and 690kPa (100 psi) except for Model XFN12 where
the minimum is 210kPa. Lower pressure will mean low ow rates. If
the inlet pressure exceeds 690kPa a pressure reduction valve must
be tted prior to the lter.
If water hammer is prevalent a water hammer arrestor must also be
tted prior to the lter.
The lter should be located far enough from any water heaters to
avoid hot water backup to the lter.
The lter must be protected against freezing water temperatures.
Backwash this unit at least weekly to prevent media compaction and
channeling.
If grit or sand is present in the water supply remove it with a coarse
(200 micron or similar) in-line strainer to prevent damage to valve
components and seals.
FAILURE TO OBSERVE THE ABOVE WILL VOID WARRANTY.
If connecting to a public water supply a backow preventer may have
to be installed - check with the water supplier.
In backwash and rinse modes there is no water supply to service.
Points to watch
1 Do not use the valve handle to tighten the head.
2 Do not sweat copper ttings to or near the valve as it may cause
damage.
3 Do not lift any lter by the valve handle, or push down on handle.
4 Do not overtighten any pipe ttings, plastic ttings are preferable.
5 A strainer needs to be installed if any sand or grit is in the water.

INSTALLATION
1 Position the lter on a at surface close to a drain or a properly trapped
outlet and in a position where the lter can service all the lines which
require ltered water. The lter should be placed far enough away
from a water heater to avoid any hot water backup into the lter.
2 Identify the inlet and outlet by the arrows moulded into the black valve.
The drain outlet is between the inlet and outlet.
3 Ensure the valve body is tightly screwed into the main tank.
4 Plumb in inlet/outlet piping, we recommend the use of unions to facilitate
removal of the valve for media recharge. Unions are essential for
neutralising lters where regular media additions are required.
5 Fit the backwash ow controller supplied, run a hose (not supplied) from
the drain outlet on the valve to a oor drain. The drain hose should not
be longer than 7 metres, be reduced or restricted, have any rises and
should have an air gap of at least 40mm at the drain entrance to prevent
syphoning and allow the backwash ow to be observed.
6 Allow tank to ll and pressurise, check for leaks and seal with thread tape.
7 Unscrew valve from body to allow addition of media. Syphon half of the
water out and slowly ll the tank with the media in the order shown below.
Replace valve making sure there is no media left on the o-ring or thread.

TO PLACE THE NEUTRALISER INTO SERVICE
1 Turn the silver lter valve lever to the Backwash position.
2 Slowly turn the water supply on.
3 When water starts to run to drain turn the water supply off.
4 Soak the media for a minimum of two (2) hours, preferably overnight,
before proceeding with the next step. Carbon lters should soak for at
least 24 hours and preferably 48 hours.
5 Ensure the lter valve is still in Backwash position. Slowly open the
water supply to start backwashing. Leave until water becomes clear at
the drain.
6. Turn the valve lever to the rinse position. Rinse until water is clear
7
Turn valve lever to lter position. The lter is now in service and ready for use.
TO BACKWASH FILTER
This should be performed at least weekly.
1 Ensure no appliances are running that require water.
2 Turn the silver handle on valve to the backwash position.
3 Run water to drain until water becomes clear or for at least ve minutes
whichever is longer.
4 Turn the silver handle on the valve to rinse. Run water to drain for at least
5 minutes.
5 Turn the silver handle to the lter position. The lter is now backwashed
and back in service.

NEUTRAFIL TOP UP
Note that most media does not need replacing on a regular basis, Neutral
is the exception as it is sacricial and designed to dissolve slowly
neutralising acidity. It is likely to need topping up every 2 months or so
depending on water use and chemistry.
1)
Disconnect the inlet, outlet and drain and power connections from the valve.
2) Unscrew the valve from the tank and remove it. The riser pipe in the
centre of the tank may lift up with valve. Attempt to minimise this.
3) Place a cap over the riser pipe.
4) Add Neutral to the tank so it is approx. 2/3 full.
5)
Ensure there is no media in the tank thread. Remove the cap on the riser pipe.
6a) If the riser pipe has lifted when removing the valve it must be moved
back down into the Neutral.
6b) Connect a hose with a suitable adapter tting to the riser pipe. A 20mm
PVC pressure elbow is suitable to connect onto the riser pipe.
E.g.
6c) Turn on the water, and push / wriggle the riser pipe pack into the tank.
The Neutral will rise up with the ow. Do not allow it to overow out of
the tank. Reduce the water ow to prevent.
6d) Once the riser pipe is back in position, turn off the water. Hold the riser
pipe and remove the adapter.
7) Ret the valve and reconnect.
8) Do a backwash and rinse.
